By Michelle M. ScottTraffic lights can change color when a signal changes.
It can also be changed at night when there’s no traffic.
When a signal goes from green to red, traffic lights change color.
When a signal turns red, the lights turn blue.
The change in color has a subtle, “gummy” sound.
A traffic light that is green at night and red at day will turn red when there is no traffic, while a traffic light changing color during the day will go from green and blue to red and blue when there are traffic.
But it doesn’t always happen that way.
Sometimes a traffic signal changes colors when a red signal is in place, or when a green signal is on.
In these cases, the signal may turn green to make room for a yellow signal, or yellow to make space for a green light.
Sometimes, when there isn’t any traffic on the road, the signals can go from red to yellow.
If you see any of these things happening on your road, make sure to stop and ask the light switch person or driver to confirm that the light is going to turn to green or red at any time.
When the light turns green, the driver should turn their headlights on and make sure they’re flashing the green.
You can also turn the lights off if you don’t want them to change colors.
If you see a green flashing in the rear view mirror, turn the car’s headlights on to make sure the red is on, too.
If the red light is on and the traffic light is yellow, turn off your headlights and wait until the light changes to green.
If a traffic sign has a yellow sign on it, that indicates it is for a red light, you’ll need to wait for the signal to change before turning it green.
If a traffic stop sign has red flashing on it and a yellow light on it indicates it’s for a blue light, turn it green and then make sure you’re not going to be pulled over.
If your traffic lights aren’t green at all, don’t worry.
Your emergency lights can still turn red to make traffic stop, so you can still use them.
